'Sparsebak'

Fast Time Machine-like disk image backups for Qubes OS and Linux LVM.

I tested the new version this morning and had worked around a few issues such as first trying to run from /usr/local/sparsebak, and then went back to square one and used /sparsebak as it was originally intended.

$ sudo /sparsebak/sparsebak.py send --save-to sys-usb:/run/media/user/USBdrive/sparsebak

I was attempting to "send" all my VM's private sections to a drive mounted on sys-usb, and I seem to have run into a problem with one particular AppVM. When it got to my vm-vault-private it printed:

"Delta map not finalized for vm-vault-private ...recovering."

and a few seconds later this exception:

"
Processing Volume : vm-vault-private
Updating block change map: Traceback (most recent call last):
    File "/sparsebak/sparsebak.py", line 1008, in <module>

FWIW I get the same error when "sending" a test VM for the 2nd time (the first backup seemed to be OK) or when using "monitor".

I'd suggest creating issues on Chris' github project page...

Done: Assert bkchunksize #3
